, 24 Claims. My present invention relates to apparatus for forminghollow glass articles; and more-particularly to apparatus for formingsuch articles efllcientiy and according to a desired cycle of operationby the use of a completely automatic machine.

In the prior art the Hartford-Empire I. S. machine represents a highlyimproved type of apparatus having a relatively desirable cycle ofoperation. This machine is practically effective to produce glassarticles of the narrow'neck'type rapidly and efliciently. It has,however, certain features, which under'certain circumstances andaccording, to certain persons may be considered as disadvantageous. Forexample, it requires the use of a chute system in distributing chargesof glass from a single source of such charges, such as an automaticglass feeder now common in the art, to the several stationary blankmolds of the forming machine. It also has the feature which incertaininstances may be considered a disadvantage, that the working level ofthe machine must be at least a predetermined distance below the level ofthe glass in the tank from which the machine is supplied with charges inorder to permit of the interposition between the tank and the blankmolds of the machine of the necessary charge distributing chute system.

In other prior art machines of the rotary type having either one or twotables, the rotating mold carrier or carriers have been of such largedimensions in order to provide for the use of the number of moldsnecessary to attain the relatively high production desired, that thedevices have been cumbersome and have used excessive power. Also adifiiculty has arisen in these devices that the radii at which the moldswere carried were so great that the centrifugal force effective on theglass while unsupported laterally by one or another of the molds tendedto swing the glass out and distort it, resulting in deformed articles.

Furthermore in rotary machines of the intermittently rotating type, themass of mechanism which had to be intermittently rotated and stopped wasin many instances so-great that the starting. and stopping inertiaconsumed large amounts of power and caused rapid wear of the parts.

My present invention seeks to attainthe advantages of some or all of thepriortypes of machines and possibly certain further advantages peculiarto the present machine as will be hereinafter set forth, whileeliminating in so far as possible the disadvantages inherent in themachines of the prior art. At the same time, my present machineis'designed for a large production as related to the number of moldsprovided on the machinev and. for the efllcient operation of such moldsaccording to a desired cycle.

Among the specific'objects of my invention is the provision of a machinehaving a plurality of rotary blank molds cooperating with a plurality ofstationery blow molds, and more specifically one in which equal numbersof blank. and ,blow' molds are provided, these molds respectivelycooperating with each other and with no other molds.

A further object of the present invention is to provide apparatus of thecharacterset forth inv which articles of the narrow neck type may bemade and in which blank molds are positioned on a relatively light,intermittently rotating carrier at a minimum distance from the centerthereof, so as to minimize the amount of centrifugalforce on the blanks.Specifically, it is desired inthis connection to. provide an apparatusin which the blanks are always enclosed in the blank molds while theblank mold carrier is rotating, thus preventing distortion of the blanksdue to centrifugal force.

A further important object of my invention is to provide peculiar and'novel transfer means including one or more reheating stations forblanks intermediate the blank' molds in which they are formed and theblow molds to which they eventually are-transferred. Specifically it isan object that one such intermediate reheating station or position/mayserve a plurality of blank molds and also that blanks from thatreheating station or position may be moved to a pluralty of the blowmolds. In this connection, it isalso an object that the transfer meansinclude specifically neck rings which are invertible according to theprinciples now in use in the Hartford I. S.'machine", thus effectingdistortionless inverting and lateral movements of the blanks, combinedwith tongs by which the blanks are moved the remainder of the distanceto their respective blow molds, and in one or more of which transfermeans-reheating will take place for desired periods of time.

A further object is to provide in a machine of the character generallyabove-set forth for the formation'of hollow glass articles in a cyclesuch that two or three, and 'under certain circumstances even four,charges of glass, all of which were supplied to the same blank mold, maybe simultaneously in the process of formation, thus using the severalmolds totheir best advantage and with a minimum of idle mold time andhence making bottles or other hollow glass articles according tothe'most advantageous cycle for each particular article being formed.

Further and more specific objects of the present invention will becomeapparent from a reading of the following description and appended claimswhen taken in connection with the accompanying drawings in which: 7

General arrangements of the machine The machine which I have chosen asan embodiment of my invention comprises a base which may be mounted inany suitable position around the factory .and on which is mounted anintermittently rotating b1ank' mold.,carrier having suitable .blankmolds thereon, the operating means for rotating this, carrier, certainof the blank forming instrumentalities, and-also a plurality ofstationary blow molds; which are arranged in afstraightline', the midportion of which is perpendicular to a line radial of the blankmoldcarrier through the transfer station thereof. Suitable transfer meansare provided including the neck ringsassociated with the blank molds,intermediate stationary tongs to which the blanks are transferred bythe, neck,

rings, one tongs serving two neck rings and two tongs which move theblanks laterally from the stationary tongs to second reheating. stationsabove and ingaxial alignment wlththe blow molds and thereafter move theblanks vertically downclosed by the blow 'molds.- Suitable finalblowing. means are provided associated ;with each blow mold. 'It will beunderstood that any desiredtakeoutmeans may be used to transfer veyor,the takeout means and. the delivery conveyor not being illustrated;

The several operating instrumentalities of my machine are shown asoperated by pneumatic pressure for air motors, although it will beunopposite each of the I circumferential grooves of the drum 8 a longblow molds, and secondary movable transfer wardly to-positions at whichthey may be,en-

The timer.

I have illustrated in Fig. 11 of'the accompanying drawings, a timergenerally indicated at T by which each of the variouswcrkinginstrumentalities hereinafter to be described are operated and theiroperation synchronized with the operations of other instrumentalities."This timer.

may be substantially the same type as is used in the commercial HartfordI. 8. machine" and disclosed in Ingle Patent No. 1,911,119, granted May23, 1933, as well as in Ingle Patents Nos.

1,843,159 and 1,843,160; both granted Feb. 2. 1932.. f The timer T isdriven from a a suitable source of power in synchronism with chine of myinvention. A single motor is pref- 'erably' employed to operate both thefeeder and" the timer for the machine.

From the pointof view tion, the timer- T maybe describedzascompris ing avalve box 1 including a plurality of' valves is independently operatedcommunicates through a A-rotating drum! 'forming'a partof the timerhason its periphery a plurality of grooves, one. valveszhln each of. the

a the feeder by which glass. charges are normally supplied to the maofmypresent :inven and a short button, asshown athmay be see I cured inany desired adjusted position.

The arrangement issuchthat when a short button engages its respectivevalve goperating-a mechanismassociated with its respective valve.

that valve will be opened to admit pressurefrom I .thecommon source ofsupply, here indicated by the pipe 5 to the, associated mechanism. ofthe forming. machine. This pressure is continuously admitted until along button-located in the same groove engages the valve operatingmecha; nism, at which time the valve is. moved to a position to cut oil.further flow of pressure from the common supply to theassociatedoperating mechanism and to exhaust pressure from that mechanism.Referencefmfl-y be. had if desired. to the Ingle patents above referredto for a more disclosure of the valves and their opcomplete eratingmechanisms, 1

. The timer T may be mounted in a manner not".

shown on orladjacent tothemachine of my pre sentinvention. or may belocated at anyposition near this machine, there being the necessarynumber'of pipe connections from the timer to the several operatingmechanisms on the machine hereinafter to be described,v It will beunderstood that where necessary, flexible tubing is used to permit ofthemovement of the operating mechanismsofthemachine.v Inasmuch as thispiping involves no invention. on my part and. ifshown.

would complicate the drawings, it has'been omitted therefrom except toindicate diagrammatically some ofthe .end' portions ofthe pipes leadingfrom the operating-mechanisms.

Stationary structure of machine-blank mold car-I Tier and operatingmeans r I The machine proper of my invention as shown in theaccompanying-drawings comprises a main base member 6 which may be acasting orother suitable rigidpartto whichthe timer T may be secured ifdesired. The base 5 is provided with r wheels 'I which may be, mountedon suitable rails 2,084,385 (not shown) or on the floor of the plant inwhich the machine is used to'facilitate movement of the machine to andfrom its operative position ad- I the furnace or tankby the feeder maybe dropped" jacent to a glass feeding device, here showndiagrammatically in dotted lines at 8 in Figs. 1 and 2.

According to my invention, I prefer to so position the machine inrespect to the feeder that charges separated from the main body ofmolten glass'in' 10 directly into the blank molds at the charging besecured in a socket portion ll! of. the base 6 5 cated 'at l5, Fig. 2.The structure thusv far deas by a pin l-l. About the column 9 the blankmold carrier generally indicated at I2 is mounted for rotation, as willbe hereinafter described. At its upper end the .column 9 has securedthereto one end ofa substantially triangular stationary upper frame l3which is also supported by a plurality of vertical columns l4. Each ofthe columns 9 and I4 is secured to the upper frame by a suitable cap andclamping bolt arrangement as indiscribed forms the principal stationaryframework of the machine and to this structure substantially all theremaining parts are attached. I

The blank mold carrier which is generally; indicated at l2 comprisesamain table member 16 which is substantially octagonal in its exteriorcontour and, is provided with'a depending skirt for attachment of theblank forming instru-' mentalities and certain of theiroperating means.The member It also has rigid and, in the modification shown, integraltherewith a central sleeve portion l1 which bears-on the center shaft 9at l8 and I9. The weight of the rotating parts of the blank mold carrieris supported on ball bearings 20 interposed between the horizontalportion of the member l6 and a suitable annular support 2| which issecured to the base 6 as by bolts 22.

Means are provided for rotating the blank mold carrier intermittently.For this purpose, there is provided a member 23 which is splined on thehub portion I! of the blank mold carrier, as best shown in Figs. 3, 4, 6and 7, and which carries rigid or integral therewith a gear 24, thelatter meshing alternately with two racks 25 and 25. The racks 25 and 26are disposed at different levels, as best seen in Figs. 2,3 and 4, andare connected at their ends by cross members 21 and 28. The member 28 issecured to the'piston rod29 of a pneumatic cylinder 30 which is in turnsecured to the base 6 as shown in- Figs. 1, 4 and 7. Pressure may beconducted to the opposite ends of the cylinder 3|] through the pipes 3|from the timer T so asto move the racks 25 and 26 at the desired times.The length of stroke of the piston rod 29 and hence of the racks 25 and26 may be controlled by a stop screw 32 threaded into the head endof thecylinder 30 and secured in adjusted position by the usual jam nut. Theposition of the racks at the ends of the stroke in either direction mayalso becontrolled by the adjustment of the connection between the crossmember 28 and the piston rod 29, the rod being threaded into this crossmember and secured in adjusted position by the jam nut 33.

Means are provided for oscillating the gear 24 vertically to move itbetween its positions in engagement with the racks 25 and'26. For thispurpose the upper portion of the member 23 is pro vided with an annulargroove 34-into which extends a pair of rollers 35 carriediby a yokeframe 36 which is pivoted at 31 to bracket eirtensions 39 f of themember 2 I and which'extends through suit-' able apertures in the member2| straddling the member 23, the yoke member .36 being connected at itsother end at 39 to the lower end of the piston rod of a pneumaticcylinder 4|! which is pivoted at 4! to a bracket extending from themember 2|.- Pressuremay be-conducted tothe through the pipes 42.

Thus the rotation of the blank mold carrier is oppositeends of thecylinder 40 from the timer T I eifected'as follows: starting with partsin the position "shown in Figs. 2 and'4, with the-piston in cylinder 30at the'left hand end of the cylinder, the first action in effecting thenext rotation of the blank moldcarrier, which is always, in acounterclockwise direction, is the lowering of the member 23, whichisaccomplished-by the-admission of pressure to'the upper pipe 42 'ofcylinder 40 from the timer. This-lowers the piston in the cylinder 40and moves the yoke member- 36 in a counterclockwise direction, loweringthe member 23 to move the gear 24 into engagement with the rack 26.Pressure is then conducted from the timer to the pipe 3| leading tothe-left hand end of cylinder 30, as seen in Fig.4, causing a movementof the pistonin this cylinder'to the right and causing the movement ofthe rack 25 to the right,

' thus rotating the blank mold carrier counterclockwise for an angulardistance corresponding to the distance between blank molds, which in thepresent case is 90. I

When it is desired to move the blank mold carrier another step in itsmovement, the member 23 is raised by the reversal of pressure to thecylinder 49 under control of the timerT to move the gear 24 intoengagement with therack 25, after which pressure is'reversed to thecylinder 30 and the piston therein moved from right'to left, bringingthe parts again to the position shown in Figs. 1 and 4. T N

Blank molds, mounting and operating means therefor As shown in Figs. 1to- 5, there is aplurality,

in this instance four, blank molds 43 mounted on the blank mold carrierwhich is generally indicated at l 2, these molds being in neckdownposition. Each blank mold is preferably formed in the usual manner incomplementary portions or halves secured interchangeably in mold carriers 44. As bestv shown in Fig. 5, the mold carriers are pivotedon acommon pintle 45 which maybeformed as a stub shaft rigidly secured inthe table member 16 as shown in Fig.4. For

convenience of construction, the mold carriers 44 may have their bearingportions received upon ,a common sleeve 46 which is in turn journaled onthe pintle 45 so that the mold holders maybe removed as aunit, if itisdesired to change them forsome purpose. The upper portions of thepntles 45 extend through an annular ring 41 connecting them together andthus insuring the rigidity of theconstruction. 3

For opening and closing each of the blank ,molds; the mold holders .44are connected by links 48 with the outer ends of a yoke 49 whichismounted for. radial movement with respect to v the blank mold carrier ona pair of parallel rods 50 secured in a hub portion of the mold carrier.The yoke 49 straddlesJhe-bearing portionsof the mold holders 44. ,Eachofxthe yokes 49 is provided with a lever 5| p voted theretoat one side,as at 52,vand,I10rrnally bearing against a fixed stop portion 53 whichis rigid or integral with the yoke 48, The lever M is continuouslyurged-ma counterclockwise direction as seenin Fig. 5-towarditsengagement with the stop 53 bya compression .lsprlng 54 extendingbetween the outer end of the lever 5i and asuitablefstop formed asv ashoulder 55 on theyoke, there being short studs concentric with the endslot the spring I and station D 54 for preventing'the displacementthere'oif.

Thedetails of the head, per se,

form no part of the present invention and may forms the piston rod of apneumatic cylinder 94-.-

The cylinder 94 et 16.

Thus the head members 89 and 90 may be moved vertically by the movementof the piston within cylinder 94, which is accomplished by admittingpressure to the upper and lower ends of the cylinder at the desiredtimes through the pipes from the timer T. It is also desired that thesettle head be moved laterally subsequent to this initial verticalmovement away from the mold and in response to its continued upwardmovement. For this purpose, the shaft 93 is provided with a laterallyextending bracket 96 carrying a cam roller 91 working in a stationarycam slot 98 formed in a part of the bracket member 81 substantiallyconcentric with the shaft 93. This construction is conventional and issubstantially equivalent to that employed in the commercial "Hartford I.S. machine shown is suitably secured to the brack- 0 and described inthe Ingle Patent No. 1,911,119,

above referred to. Settle blowing pressure may be conducted to the head89-90 through a pipe- 99 from the timer T and thence through thepassages shown in Fig. 3 in the conventional manner to the underside ofthe head 89, thence through the funnel into the upper end of the mold43.

While I have shown and described a conventional type of settle blowingmechanism, it will be understood that, if desired, some other means ofsettling charges in the blank mold may be* employed, for example thesettle plunger mechanism shown and described in the Rowe Patent No.1,945,983, granted Feb. 6, 1934. This or any other type of blankformation may be employed within the purview of the appended claims.

Also, while in the machine of the accompanying drawings I have shownsettle blowing as occurring at station A, it will be understood that ifdesired the blank molds may be charged and the charges settled thereinby any desired or conventional means at station B, the only changesnecessary for accomplishing this purpose being to provide for thefeeding of the molds at this station and to move various mechanisms forforming blanks and hereinbefore described, including the funnels, neckpin and its operating mechanisms, and the settle blow head and its"operating mechanism from station A to B. Certain other variatiohereinafter to be set forth may be resorted to within the scope of theappended claims.

The counterblowing means, construction and operation I have shownthecounterblowing means at B and C, if the charging takes place asparticularly illustrated at station A. In any event, the

I a vertical shaft to the base same orsome equivalent counterblowingmeans may be used whetherthese means be located at stations. 13 or C, orwhether they be duplicated at both stations.

Pressure may be supplied to the oppositeends of the cylinder H4 through the pipes I I1 from the timer T formoving the counterblow head I I0 vertically to and from its operativeposi-' tion at the desired times.

The neck rings, mounting and operation In the apparatus of my invention,the neck rings are utilized first in the formation of blanks as aboveset forth and later in transferring the blanks from the "blank moldspart way to the blow molds. They are'also utilized in inverting theblanks from a neck-down to a neck-up posh tion.' There is one neck ringfor -each-{of the blank molds andeach of the neck rings is inde'pendently invertible and isprovided withits in- 1 dividual opening andclosing means movable therewith". 'I'his means normally tends to retainthe neck rings resiliently closed, there being v a single means notpartaking of .the movement of rotation ofjthe blank mold carrier foropen-- ing the neckririgs. Y 1

As shown, the blankmold carrier is provided with oppositely arrangedbrackets I I8 by which' the neck rings are carried. Each of the bracketsII8 supports a transversely extending substantially horizontal pivotshaft H9, this shaft form-.

shown I (Fig. 5) the neck rings'associated with the moldsat stations Cand D are both mounted on a single pivoted shaft II9. Surrounding eachextending end of this shaft are rotatable collars I20 and I2I' which areretained onthe shaft by suitable relatively stationary collars I22 andI23 which are pinned to the shaftII9.

which the holders I26 for one of the neck'rings are mounted, as bestshown in Flgs."1,'3 and 5. The neck ring is shown in its invertedposition in Fig. lin a manner to show the holders thereof and theirpivotal arrangement on the arm'I24. The neck ring 61 is'formed as in theusual manner in mating halves, the halves being supported in the holdersI26 by suitable means(not shown); The vertical adjustment between thearm I24 and the collar I2I compensates for blank molds of differentheights, there being suitable means such as a screw (not shown)forholding these "parts in adjusted position.

. Means are provided moving with each heck ring for holding itclosedunder resilient pressure for the major'part of the cycle and for 'cooperation with the single opening means later to be described atthe desiredtime. As shown (Fig. 5),

the neck ring holders I26 are connected by links I21 with a commonpintle I28 which is mounted on the end of alever I29 pivoted at I38 tothe arm'l24." A tension spring Ill extends between a fixed anchorage onthe arm and a point on the 7 lever I29 and tends at all times to retainthe neck ring closedi The end of the lever I29 opposite the pintle I28is provided with an upstand ing portion I32 for engagement by the openinmeans hereinafter to be described. i

It will be understood that the neck ring shown 1 in Fig. 5 cooperatingwith the mold at station C is arranged in exactly the same way as thatat station D and is supported by the arm I33 corresponding to the armI24, there being equivalent mechanism and adjustments for this neck ringand the operating lever I34'associated therewith corresponding to thelever I29 and'havingan upstanding portion I35 for engagement by theopening means later to .be described.

Means are provided for inverting the neck rings 0 from theposition whichthey occupy during the formation of ablank, that is, with the neck ringpositioned as; shown in Fig. 3 resting on the bracket 68 to the positionshown at the lower right-hand portion of Fig. 1. For this purpose eachneck ring holding sleeve, such as' I2Il and The collar I2I hasvertically adjustably securedthereto anarm I24 which in turn carries thepintle I25 on station 'D inthe transfer position.

I Therollers I88 are arranged tobe moved by the rotation of :the blank moldcarrier into an annular groove formed by a spoohlike member I40 securedto the upper; end of a piston rod I of a vertically disposed pneumatic,cylinder"l42. Pressure is conducted to the opposite ends of thecyllnderI42 from the timer T through the pipes I48. I The leading neck ringsassociated with each of the brackets. I I8:, that is the .neck ringsassociated with the molds at stations B and D at the position of theparts shown in Figs; 1 and 5, are operated for inversion by the cylinderJ42 and move the blanks from the position D to the position Eshown inFigs. 1, 2 and 8. The following neck rings, that-is the neck, ringsassociated with the molds shown positioned at stations A and C in Figs.1 and 5, are arranged to transfer blanks from their respective moldswhen those molds are at station D to another reheating station shown atF in Fig. 1. The operation of these neck rings and their inversion isexactly the same asfthat justdescribed, but they are operated by adiflerent cylinder cooperating with the rollers I44 on p the lower endsof their operating racks ;I45.

These rollers I44 are moved byzthe rotation of the-blank mold carrierbetween the endsof a' spool-like member I46 mountedonthe'piston rodbeing controlled by the timer in exactly the same way as is theoperation of cylinder I42... y

Blanks are transferred fromthe blank. molds at station D and to stationsE or F in alternation and according to whether the leading or thefollowing neckring is associated with the mold at reheating stationsEand F are each common to two blank molds, that in station E cooperating.with the blank molds shown in Figs. 1 and 5 at B and D andthatatstation F cooperating with the Thus the.

'At each ofgstations E and F, there is a stationarytongs hereinafter to be described in whichthe blanks are held forreheating, although as will appear hereinafter it may under certaincircumstances be unnecessary to providethese tongs should it be desiredtovmake up a machine without having as long a reheat period as isprovided by the machine herein particularly described Means are providedaccording to my invention for opening the neck rings after they haveinverted and transferred the blanks to, stations E or F, as the case maybe. For-this purpose, there is portions I82 and I35 of a. neck ringwhich is'at either of the positions E or F. The portions I32 and I 35 ateither of these stations will be engaged by the outer ends I48 or I49,Figs. 8 and 9 of levers I5IIor I5I respectively. These levers arepivoted intermediate their ends at I52 and I53 I respectively. The innerends of these levers are connected bylinks I54 and I55 respectively to aprovided means for engaging the upstanding cross head I56 which issecured to the outer end a of the piston rod extending from a pneumaticcylinder I51; The cylinder I51 is provided with an upstandingsocketportion I58 which is connected by a suitable set screw I59 to the lowerend of a depending shaft I60 secured to the upper frame I3 asillustrated in Fig. 1. The-pintles I52" end portions I48 and I49 oflevers I50 andI5I to move to the right as seen in Fig. 8. At this timeone of these outer end portions will be in engagement with theupstanding portion I32 or I35 respectively of a neck ring which has beenin-' verted from the position it occupied during the formation of theblank therein and the stationary tongs hereinafter to be described willhave closed about the blank beneath the neck ring. The neck ring inquestion will then be opened as" above set forth to release the blankafter which the neck ring inverting means will again operate to returnthe neck ring back to its position for the formation of the nextsucceeding blank. Once the inversion has progressed sufilciently sothatthe contact portion 132 or I35 clears the end portion I48 or. I49respectively, the neck ring will again be closed under the action of itsspring I3I. At any desired time subsequent to this returning of the neckring, the neck ring opening levers I50" and I5I may be returned to theirinitial position under the tension of springs I63 or I64, which areconnected respectively between levers I50 and I5I and stationaryanchorages on the cylinder I 51.

Stationary tongs at the first reheating station At each of the reheatingstations E and there is preferably a stationary tongs for receiving theblanks from the neck rings and holding them for a desired period at thestationary positions for reheating. Inasmuch'as these tongs are eachsimilar to the other, only one will be de-' scribed.

Referring to Fig. 8, I have shown at.I65 the. stationary tongs atstation E, these tongs being suitably secured to tong holders journaledabout a common pintle I66, which is carried by a w bracket I61 securedto the lower end of a depending shaft I68, which is secured as bestshown in Fig. 2 to the upper stationary frame I3. The

shaft I68 is also steadied in its position by a cross bracketIBQ (Fig.2) extending to one of the vertical shafts I4; 1 For operating the tongsI65, theyare connected by links I10 with a common pintle carried by apiston I1I in a pneumatic cylinder I12. Pressure may be supplied to oneend of this cylinder, as shown, through a pipe I13 from the-timer T formoving the piston in a direction to close the tongs. Opening of thetongs may be efiected as shown by means of one or moretension springs I14 connected between the piston HI and a' fixed anchorage on thecylinder I12. Thus, opening of the tongs willbe effected by the springI14 upon exhaustion of the pressure by the timer through pipe I13,

Vertical adjustment of the tongs I65 may be eifected to compensate fordifierent' heights of blank molds and consequently difierent verticaladjustment of neck ring arms as I 24 in respect to the sleeve I'll (seeFig. 2) by a vertical adwhich is carried by and rigid with the "sideringFigs. 1, 2, 4, 8 and '10, at I16, these tongs being verticallyadjustably -50 cylinder I83.

At thistime the neck pin "ii is elevated, theneckfringand the blank mold atstation A areclosedf The settle blow head 89 is then'lcwered to the:position shownin Fig-3 iromtheposition in 2,084,285 Fig. 1 by theadmission'of pressure from the end of the cylinder 14 (Fig. 3). 'Theblank mold with the settled blank therein is then moved from station Athrough station B to station C without further action thereon according.to the 15 disclosure of the machine in the accompanying drawings,although attention is called to the sugested alternatives hereinabove'At the station 0 the counterblow baiiielllfl is lowered to engage andclose the upper end of the blank mold and the counterblow head II 6 israised, bringing the parts to the position shown in Fig. 3. by theadmission of pressureito the upper end of cylinder I66 and to the lowerend of.cylinder I respectively as shown in Fig. 3. Counterblowingpressure may then be supplied through pipe H2 to counterblow the blankin the usual manner. After the counterblowihg has been carried on forthe desired time, pressure is reversed in cylinders I06 and Illto movethe counterblow baflle I00 and counterblow head II 6 to their respectiveinoperative positions. The mold with the blank being considered thereinis then moved from station C to station D by the rotating means for theblank mold carrier hereinabove described. At station D, the blank moldis opened and simultaneously. the blank mold at station A is closed bothunder control of cylinder 65, pres-' sure to which is'controlled by thetimer T. The blank is now in readiness for its transfer, which isaccomplished by swinging the neck ring-holding the blank therein, asshown from station D to stationE, this being accomplished by theadmission of pressure to the lower end of cylinder I42, and moving theparts to the position shown in Figs. 1 and 2. The stationary tongs IE5at station E are then closed by the admission of pressure from the timerthrough pipe I13 to cylinder I12 (Fig. 8), so that the blank is nowengaged both by the neck ring and the tongs-I65. The neck ring holdingthe blank is then opened under the control of cylinder I51 by admittingpressure from the timer to the right hand end of this cylinder as seenin Fig. 8. The blank is now held in the tongs I65 at station E and theneck ring may then be brought back to its normal position at station Eby reverse movement of the piston in cylinder I42. The blank mold maythen be moved from station D to station A and closed at station A, ashereinabove described, in readiness for the receipt of the nextsucceeding blank in that mold, which is formed as aforesaid.

The blank at station E reheats for the desired length of time. At anytime during this'firstreheating period, tongs I16 associated with theblow mold at station G are moved to engage beneath the tongs I65 atstation ,E and support the'blank at this station. The tongs I65 may beopened once the blank is supported in tongs I16 and at the terminationof the-first reheating period the blank is moved from station E tostation L by'movement of the tongs I16 angularly about the vertical axisof the column I4. The blank continues to reheat at station L (the secondreheating station) fora desired period These operations are accomplishedof time at the termination of which it is lowered into the blow mold atstation G, which is open at that time to receive it, the blow head 201being at its inoperative position during the lowering of the blank intothe mold.

The blow mold at station G is then closed about the blank by theadmission of fluid pres sure to the left hand end, as seen in Figs. 1and 2 of cylinder 263associated with the blow mold at station G. Thetongs I16 may then be opened to release the blank to the blow mold andmoved back to receive the next succeeding blank at station E asaforesaid. The blow head 261 associated with the blow mold at station Gis then moved laterally and simultaneously lowered to its operativeposition and final blowing pressure is supplied from the timer throughthe pipe 268 and the blow head 261 to final blow the article at stationG, This completes theformation of a single blank, H

Also, from the foregoing, thegeneral cycle of the machine in forming aplurality of blanks should be obvious, but here again it will besummarized at this time for the purpose of clarity.

The machine as disclosed comprises four blank molds and four blow molds,there being ,a neck ring associated with each of the'blank molds, twointermediate stationary tongs, and, four secondary tongs, one of whichis individual to each of the four blow molds. The arrangement is suchthat eachblank mold always supplies blanks to a single blow mold and.alternate blank molds supply blanks to the stationary tongs at stationsE, the remaining blank molds supplying blanks for transfer to station F.

As a result of this manner of operation, all but one of the blank moldsmay be simultaneously occupied in forming blanks, the .stationary tongsat stations E and F mayalso be in operation simultaneously, the movabletongs I16 associated with the respective blow molds may also be inoperation simultaneously, and the final blow molds may also be inoperation for substantially the entire time. Y r

Under these circumstances twoor three, and even four, blanks, all ofwhich are formed from charges supplied to the same blank mold, may besimultaneouslyin the process of formation into completed articles. Forexample, one blank mold maybe located at station A and a charge of glassmay have been supplied thereto. The

, immediately preceding blank formed in the same blank mold may besupported in the stationary tongs I65 at station E; The nextvprecedingblank formed in the same blank mold may be supported in tongsI16 at station L. The fourth or next preceding blank. formed in the sameblank mold may be enclosed in the blow mold at station G. This situationor one closely parallel thereto may exist as to each of the other blankmolds at some time in their normal cycle 10f operation of the apparatus,Thus, for each of V the blank molds there will be a time in the normalcycle of the machine when two or three, and even four, charges of glassmay be simultaneously in -the process of formation, all of these chargeshaving been successively supplied to the same blank mold. 5

All this makes for a very emcient utilization of the time of the severalmolds provided on the machine, as well as for the provision of a desiredcycle of operation from the point of view of the glass, advantage beingtaken of the several tongs to sustain the blanks for the necessary ordesired Conclusion 5 While I have shown and described but one embodimentof my invention in detail in the foregoing description and accompanyingdrawings, it will be obvious that many changes in details and inconstruction may be made, all without departing from the spirit andscope of my invention. I do not wish tobe limited, therefore, except bythe scope of the appended claims, which are to be construed as broadlyas the state of the prior art permits. I claim: a I
